Need a new radiator?
Hi Guys, ....so, my jeep has been overheating lately intermittently. at first i thought a bad sender or thermostat since it will go down instantly once i turn off-on the car. then did it a couple of times more and the coolant was boiling in the reservoir tank. while on the expressway everything was fine and once on the streets it would do t again. i figure out that if i would put it in neutral and rev up the temp will go down. so i open the radiator cap and there was this rusty mud everywhere (i forgot, coolant was also brownish rusty color) so i did a system flush and clean and nothing changed, so my next step is shop for a good radiator. what is your experience on radiators, what will be a good option and i guess i should go all aluminum? i am throwing a new Thermostat, thermostat housing and new water pump for peace of mind. all suggestions on radiators are greatly appreciated.

It sounds like it was long over due for a flush so it's good you did that, but before you replace the radiator have you tried replacing the radiator cap? If it's not holding the correct pressure it will boil over.

yes, it was gifted to me a year and a half ago and i started lifting it and working on it. Not my daily driver, just a rarelybused hobby car. Supposedly the person who had it before tookbgood care of it but definitely it was overdue. No; i have not tried the cap, but anyways for peace of mind will do everything.

All aluminum isn't important, my 20+ year old factory radiator with well over 200K on it wasn't cracked or leaking when I replaced it, the only reason I did replace it was because the fins were falling apart. If you do some research you will find that quite a few people have issues with overheating after switching to an all aluminum radiator.

I'm running a cheap ASI aluminum with winch and license plate blocking radiator.
Runs cool too cool. I replaced water pump and t stat at same time also got rid of coolant tank and all under hood junk on my 89.
It was a much needed upgrade hd coolant lines leking at heater core radiator itself leaking. Only thing i dont like is the asi radiator cap.

Before you go to the trouble of replacing the radiator and water pump and hoses, do yourself a favor and flush the system multiple times until it is clear of rust and debris. A new radiator won't make a difference if it gets clogged up with junk. Even if you have to flush it several times using water only, just make sure it is clean.
